United States Patent O 3,106,347 ADJUSTABLE DEFLECTOR FOR A SPRAY NOZZLE Stanley A. Hayes, Arcadia, Calif., assigner to Hayes Spray fGmr Company, Pasadena, Calif., a corporation of Caliorma Filed May 1, 1961, Ser. No. 106,818 7 Claims. (Cl. 239-505) The present invention relates to spraying nozzles and rnore particularly to an apparatus for controlling the type of spray issuing from such nozzles.

Spraying devices 'are well known in which a deiiector is arranged to project into the discharge stream from the nozzle for providing a preselected spray pattern. Such conventional spraying devices have several disadvantages. First, the discharge stream may be deflected into only one spray pattern if the deiiector is used. Second, if a solid discharge stream is desired, the deflector must be removed from the discharge nozzle and hence may be easily lost.

A spraying device capable of providing several diiterent spray patterns is needed when many diiferent types of plants, shrubs, trees, etc. are to be sprayed with different chemicals, for example, in the control of garden insects and diseases.

In accordance with the present invention, an adjustable deflector spraying device is provided for a discharge nozzle in which a deliector is provided for deiiecting the discharge stream in the formof a spray an-d means are connected between the deilector and the discharge nozzle for eccentrically and rotatably mounting the deflector on the ldischarge nozzle relative to the discharge stream whereby the type of spray pattern may be readily controlled by rotating the deflector. In the apparatus of this invention, an infinite number of stream patterns may be obtained.

The invention is described in more detail in reference to the accompanying drawing in which:

FIG. 1 is across sectional view of an apparatus in accordance with the present invention;

FIG. 2 is a plan view of the apparatus of FIG. 1;

FIG. 3 is an end view of the apparatus of FIG. 1;

FIG. 4 is a plan view of another embodiment of the present invention; and

FIG. 5 is a cross sectional View of the apparatus of FIG. 4.

Referring now to the drawing and more particularly to FIG. l, there is illustrated a discharge nozzle in the form of a housing 10. The housing 10 1defines a liquid passageway 12 therethrough betweenlan inlet port 14 and an outlet -or discharge port 16. The housing 10 may be connected to a suitable source of liquid under pressure such as a conventional garden hose by means of the eX- ternal threads 18. A deflector holder 20 is rotatably mounted on the housing :adjacent the outlet end as shown. A guide pin 22 is secured at one end to the deiiector holder 20 .and at the other end projects into an annular guide groove 24 in the housing 10 adjacent the outlet end 16. The guide pin 22 `and the cooperating guide groove 24 permit the `deileotor holder 20 to rotate relative to the housing 10 while preventing longitudinal movement between the housing 10 and the holder 20.

The 'deflect-or holder 20 is provided with an annular bearing surface 25 which is eccentric to the discharge stream or the longitudinal axis x--x of the discharge nozzle. A `dellector ring 26 is rotatably mounted on the annular bearing 25. A curved deflector blade 28 is suitably secured to the deflector ring 26 by brazing, welding, etc. ,for detlecting the discharge stream in the formof a spray `as will be more fully described. A guide pin 30 is secured 'at one end tothe deflector 2S andthe deiiector ring 26 and projects inwardly therefrom to engage 3,106,347 Patented Oct. 8, 1963 'ice an annular guide groove 32in the surface 25 of the deiiector holder 20 to prevent longitudinal movement between the dellect-or ring 26 and the deliector holder 2li.

The housing 10, the deflector holder 20 and the deflector ring 26 may have 'an externally knurled portion 36, 37 tand 38, respectively, to raid the operator in rotating the several parts.

In operation the deliector ring 26 and the deflector 2-8 are rotated relative to the deilector holder 2li to control the degree of stream interception by the deflector and thereby the spray pattern issuing from the discharge nozzle. In the position of the deiiector 28 'as shown in FIGS. 1 and 3 the .detlector 28 does not intercept the discharge stream which results in a solid stream issuing from the nozzle. When the deflector 28 is rotated 180 it is positioned for the maximum discharge stream interception. By rotating the deflector 2S relative to the deflect-or 20 aninlinite number of spray patterns rnay be obtained.

To control the angle of the spray pattern issuing from the deflector relative to a horizontal plane, the deiiector holder 20 is rotated relative to the housing 10;

Referring now to FIGS. 4 and 5 there is illustrated a modiiication of the apparatus of FIG. l in which a deiiector holder 40 is rotatably mounted on a housing 42. The housing 42 includes an external-ly threaded portion 44 for connection to a hose or the like. A guide screw 46 is secured to thehousing 40 and extends inwardly therefrom to engage a guide groove 48 in the housing l2 to prevent longitudinal movement between the dellector holder 40' and the housing 42 While permitting rotary motion therebetween. A deilector ring Sil including la bell shaped or truste-conical end portion 52 is rotatably mounted on the deflector holder 40 by means of a guide screw 54 which cooperates with an external guide groove 56 on the deliector holder 40 as shown. An O-Iing 58 is also `disposed in an external groove in the deiiector holder 40 to prowde a frictional torce between the deeotor holder 40' andthe deflector ring 50' which resists relative rotation between the inem-bers. The frictional force provided by the O-ring 58 prevents the deilector ring from rotating relative to the deilector holder 40 once it has `been rotated to a desired position by the operator. A deflector 6) is connected to the dellector ring 40 by means of a rivet 62 and is disposed within the bell shaped end portion 52 of the dellector ring 50. As is shown, the deliector ring 50 is eccentrically mounted on the rdeector holder 40 so that when the detiector ring 50 is rotated relative to the deector holder 4t) the deilector 60v intercepts various porti-ons of the stream issuing from the ldiscliarge port or outlet 64 of the housing 42. In the position shown in FIG. 5, the deflector 60 is positioned out of the path of the discharge stream. The deflector ring 50 with the bell shaped end portion 52 which shields the :deliector 6d prevents damage to the i deector 6l)` when the nozzle is dropped or dragged over the surface of the ground.
